Oil is an organic material. It was formed millions of years ago from the remains of dead organisms. Today, oil spills in oceans are a big problem as they harm marine life in ocean ecosystems. The spills need to be cleaned up quickly. One way to do this is to use bacteria that “eat” the oil.

Suggest two ways in which oil spills damage marine ecosystems. You may do some research to help you.
